The last thing that you would ever want to happen the night before your wedding is to receive to receive screenshots of racy text messages that your soon-to-be-husband sent to another woman. But that’s exactly what happened to a woman named Casey, who handled the nightmare scenario in the fiercest way possible.

According to her essay, which was published by the Australian news site news.com.au, she had been sure that her fiancé, whom she had been dating for six years, was the love of her life (she calls him “Alex” in the piece, though that’s not his real name).

“I felt he was The One instantly. Our families became friends, our lives were entwined, and I believed we’d live happily ever after,” she wrote.

Then, on the eve of her wedding day, she was sitting in a hotel room with friends when she got the text message that changed everything. An unknown number had sent her selfies of Alex with another woman, along with screenshots of some of the texts he had sent her, ending with a simple question: “I wouldn’t marry him. Will you?”

The contents of the messages were sickening:

“This weekend. You and I. It is on, hot stuff. Bring your A game.”

“Your body is [so] incredible. And [boy] do you know how to use it. I wish my GF had half the skills you do.”

“I miss you so much. I can’t stop thinking about…you. I’ve never had this kind of connection before.”

She burst into tears.

“Every word like a dagger in my heart,” she wrote.

Her friends were furious and insisted that she call her cheating fiancé immediately to tell him the wedding was off, but she was so shocked and confused she just couldn’t bring herself to do it. Plus, what about all of those people who had traveled to attend a wedding that was only hours away?

She didn’t sleep all night, but by the morning, she had made a firm decision about just what she was going to do.

Casey walked down the aisle in her wedding gown, and when it came time for them to do her vows, she turned to all of their friends and family members and said, “There will be no wedding today. It seems Alex is not who I thought he was.”

Then she took out her phone and read the text messages that he had sent this other woman out loud.

“With each word, more color left Alex’s face,” she wrote.

Crying, she looked him in the eyes, but said nothing. Instead he simply stomped out of the church as his family looked on, horrified.

According to the article, she turned to her guests once more and said, “I love all of you and as horrible as this is I’m glad you all are here. There will not be a wedding reception today, but instead, there will be a celebration of honesty, finding true love and following your heart even when it hurts.”
